fyi. pretty much everyone here was a noob like you at one point and only knew jl, kicker, RF, alpine. and everyone here took the recomendations they were givin and purchased a sub that wasnt the main stream, and they have never heard before. and they have never looked back. there is a reason why no one here runs that sh1t, because much better can be had. there are alot of subs in the 1krms range i would run way before a w7. for example. dc level 3, incriminator audio death row, b2 audio HN, tantric sounds md, ssa icon, sundown sa series. and there are many many more.
